ISO 14644-7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments [3] ISO 14644-8:2022(en), Cleanrooms and associated controlled environments — Part 8: Assessment of air cleanliness for chemical concentration (ACC) ISO 14644-9: Classification of surface particle cleanliness [3]
A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
Air showers are typically placed between a gowning area and cleanroom; after workers don appropriate garb and personal protective equipment, they enter the shower so that the pressurized air nozzles remove any residual particles from coveralls. Once the program cycle is complete, users exit through a second door into the cleanroom.
A common controlled environment aerosol particle counters are used in is a cleanroom. Cleanrooms are used extensively in semiconductor device fabrication, biotechnology, pharmaceuticals, disk drives, aerospace and other fields that are very sensitive to environmental contamination. Cleanrooms have defined particle count limits.
Although the clean-room approach had been used as preventative measure in view of possible litigation before (e.g. in the Phoenix BIOS case), the NEC v. Intel case was the first time that the clean-room argument was accepted in a US court trial. A related aspect worth mentioning here is that NEC did have a license for Intel's patents governing ...

A cleanroom suit, clean room suit, or bunny suit, [1] [2] is an overall garment worn in a cleanroom, an environment with a controlled level of contamination. One common type is an all-in-one coverall worn by semiconductor and nanotechnology line production workers, technicians, and process / equipment engineers.
